The SLC19A3 gene provides instructions for making a protein called a thiamine transporter, which moves a vitamin called thiamine into cells. Thiamine, also known as vitamin B1, is obtained from the diet. It is involved in many cellular processes, and is necessary for proper functioning of the nervous system. Molecules made from thiamine are important in the breakdown of sugars and protein building blocks (amino acids). Thiamine is also involved in the production of certain chemicals that relay signals in the nervous system (neurotransmitters).

Hereditary spherocytosis
Hereditary spherocytosis (HS) is an inherited condition of red blood cells. The disease can be mild and go unrecognised in some people. In others there may be severe anaemia requiring regular blood transfusions. Some people with hereditary spherocytosis may be offered surgery to remove their spleen. This usually helps the condition, but increases.
